JavaScript - Javascript For Loop
Trying to use a "for" loop to cycle through an array and compare values; if the values are equal, then it displays a message about the team, etc.
Code: <html>
<head>
<title>Javascript Colors!</title>
<script type="text/javascript">
var teamcolors = ["blue","orange","Auburn Tigers","Yuck!","black","red","Georgia Bulldogs","Congratulations!","yellow","black","Georgia Tech","Awesome!"]
function changeBGColor()
{ document.body.bgColor = prompt("What color should the background be?","Put ANY color here!");
checkForTeamColors();
}
function changeTXTColor()
{ document.getElementById("text").style.color = prompt("What color should the text be?","Put ANY color here!");
checkForTeamColors();
}
function checkForTeamColors()
{ var bgcolor = document.body.bgColor
var txtcolor = document.getElementById("text").style.color
var loopcount = 1
while (loopcount <= 12)
{ if ( (bgcolor == teamcolors[loopcount] && txtcolor == teamcolors[loopcount + 1]) || (bgcolor == teamcolors[loopcount + 1] && txtcolor == teamcolors[loopcount]) )
{ alert("You have picked the team colors of " + teamcolors[loopcount + 2] + ". " + taemcolors[loopcount+3]) }
loopcount = loopcount + 4;
}
}
</script>
</head>
<body>
<p id="text" align="center">This text will change color if you want to. <br> Maybe try a certain combination, like Orange and Blue, or Red and Black?<br></p>
<button onClick="changeBGColor()">Click me to change the BG Color!</button>
<button onclick="changeTXTColor()">Click me to change the text Color!</button>
<p id="variables"></p>
<script type="text/javascript"
document.getElementById("variables").innerHTML = ( bgcolor + " " + txtcolor )
</body>

Similar TutorialsHi Chaps, I have a PHP loop script that returns Job Information for each Project. What I've got so far is an Export to Excel (2007) function that displays the Project information on 1st tab, and the Job information on the 2nd. The problem I've got is that the Export to Excel function, gathers the information from the HTML table ID, but when looping through the data (resulting in more than 1 Job for a Project), the only way I can differentiate is to use some PHP code, something like: Quote: id="tbl_job_<?php echo $job_id; ?>" What I basically want is to store the information for each Job on a different Excel tab. But whart I have seems to break the javascript: Code: <script language="javascript" type="text/javascript">
function ExportToExcel() {
var xlApp = new ActiveXObject("Excel.Application");
// Silent-mode:
xlApp.Visible = true;
xlApp.DisplayAlerts = false;
var xlBook = xlApp.Workbooks.Add();
xlBook.worksheets("Sheet1").activate;
var XlSheet = xlBook.activeSheet;
XlSheet.Name="Project";
// Store the sheet header names in an array
var rows = tbl_project.getElementsByTagName("tr");
var columns = tbl_project.getElementsByTagName("th");
var data = tbl_project.getElementsByTagName("td");
// Set Excel Column Headers and formatting from array
for(i=0;i<columns.length;i++){
XlSheet.cells(3,i+1).value= columns[i].innerText; //XlSheetHeader[i];
}
//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
var d = 0;
for (r=4;r<rows.length+3;r++) { // start at row 2 as we've added in headers - so also add in another row!
for (c=1;c<columns.length+1;c++) {
XlSheet.cells(r,c).value = data[d].innerText;
d = d + 1;
}
}
//autofit the columns
XlSheet.columns.autofit;
xlBook.worksheets("Sheet2").activate;
var XlSheet2 = xlBook.activeSheet;
XlSheet2.Name="Job";
// Store the sheet header names in an array
var rows = tbl_job.getElementsByTagName("tr");
var columns = tbl_job.getElementsByTagName("th");
var data = tbl_job.getElementsByTagName("td");
// Set Excel Column Headers and formatting from array
for(i=0;i<columns.length;i++){
XlSheet2.cells(3,i+1).value= columns[i].innerText; //XlSheetHeader[i];
}
//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
var d = 0;
for (r=4;r<rows.length+3;r++) { // start at row 2 as we've added in headers - so also add in another row!
for (c=1;c<columns.length+1;c++) {
XlSheet2.cells(r,c).value = data[d].innerText;
d = d + 1;
}
}
//autofit the columns
XlSheet2.columns.autofit;
// Make visible:
xlApp.visible = true;
xlApp.DisplayAlerts = true;
CollectGarbage();
//xlApp.Quit();
}

This is the bit I think I need to change to get the JS to work, but I'm a bit out of my depth! Quote: xlBook.worksheets("Sheet2").activate; var XlSheet2 = xlBook.activeSheet; XlSheet2.Name="Job"; // Store the sheet header names in an array var rows = tbl_job.getElementsByTagName("tr"); var columns = tbl_job.getElementsByTagName("th"); var data = tbl_job.getElementsByTagName("td"); Any helpor guidence would be awesome! What I am trying to do is when a user click on an image button, 10 new windows will oppen. So, I created a For Loop function for that. Here is my code below: function clickk () { for (i=0; i<=10, i++) { window.open('annoying1.html','Annoying LOL','width=900, height=900') ;} } However, the window does open but not 10 times. Can you help me? Thank you... Hi guys I have what i think is a fairly simple script used for an image gallery with a next and back button. It seems to work pretty well, but i would like to make the gallery scroll round... ie when the user reaches the last picture and presses the next button again, the first image will be displayed again - and visa versa with the first image and the back button. Below is my JS, can post the small amount of HTML that calls it if necessary. Any help MUCH appreciated, been messing around with it for ages and being the newbie i am, can't seem to find any way of doing it Code: // List image names without extension
var myImg= new Array(6)
myImg[0]= "performance2011";
myImg[1]= "performance2005";
myImg[2]= "performance2006";
myImg[3]= "performance2007";
myImg[4]= "performance2008";
myImg[5]= "performance2009";
myImg[6]= "performance2010";
// Tell browser where to find the image
myImgSrc = "../images/";
// Tell browser the type of file
myImgEnd = ".jpg"
var i = 0;
// Create function to load image
function loadImg(){
document.imgSrc.src = myImgSrc + myImg[i] + myImgEnd;
}
// Create link function to switch image backward
function prev(){
if(i<1){
var l = i
} else {
var l = i-=1;
}
document.imgSrc.src = myImgSrc + myImg[l] + myImgEnd;

var l = i+=1;
}
document.imgSrc.src = myImgSrc + myImg[l] + myImgEnd;
}
// Load function after page loads

Hey all, I need help creating a Javascript loop which posts a single static comment to all videos on a website(unless another language would prove to be a better alternative?) I'm not sure where to start and although I have an idea, my lack of programming skills have left me to turn to forums...any help would be greatly appreciated. *not asking for coding necessarily. Links to relative information pertaining to such a program/"loop", and any comments helping me understand what I'm trying to do would be great...I'm just not sure what to search for lol.

This is driving me crazy. I simply want to display the values of the checkboxes with a specific name. This loop executes only once, then stops, showing no error msg. I have found no similar problem elsewhere on the net and have done a ton of tests, but cannot find out why it won't continue to loop. I've included the whole html file. Please Help! Code: <HTML>
<SCRIPT language="JavaScript">
function test1()
{
var chkLen=document.frmTable.CHK0.length;
for (k=0;k<chkLen;k++)
{
//execution stops after one loop. no error msg.
document.write(document.getElementsByName('CHK0')[k].value);
}
}
</SCRIPT>
<FORM NAME=frmTable>
<TABLE BORDER=1>
<TR>
<TD><INPUT TYPE=CHECKBOX NAME=CHK0 VALUE='one'>1</TD>
<TD><INPUT TYPE=CHECKBOX NAME=CHK0 VALUE='two'>2</TD>
<TD><INPUT TYPE=CHECKBOX NAME=CHK0 VALUE='three'>3</TD>
</TR>

I have am currently taking over as the developer for this web site, and the developer who left the project unfinished wrote a script. What it does is takes posts from vBulletin forums, for instance News posts, and then it grabs the posts by ID and Title and writes the title on the home page of the web site. The problem right now that I have is the test wraps, you can see what I mean here http://www.netcodeilluminati.com/v2 If you look on the left, I want to make the text cut off after a certain amount of characters with "..." at the end as if there is more to the title but you can't see it. Here is the script: for (x = 0; x < 5; x++) { document.write("<li><div class=\"li_icon\"><img src=\"images/icons/text.png\" alt=\"text\" /></div><div class=\"li_text\">"); document.write("<a href=\"../forums/showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a></div></li>"); } I was wondering how I could go about doing this. Thanks for any future help. -Kevin i know there are pre-made scripts to do what i'm doing. i want to create this myself to learn. i'm trying to create a list of section titles with arrows next to them, clicking on an arrow expands the section to read it's text, clicking on the arrow again collapses the section text. additionally, i would like an "expand all" and "collapse all" link and that's where my issue baffles me. my js - Code: function expandAll() {
var collapsedDivs = document.getElementsByClassName('collapsed');
for (var i=0; i<collapsedDivs.length; i++) {
var expandMe = collapsedDivs[i];
expandMe.style.display = 'block';
expandMe.addClassName('expanded');
expandMe.removeClassName('collapsed');
document.getElementById('arrow_'+i).innerHTML = '<img src="../media/hide.gif" />';
}
}
my html - Code: <div style="float:left" id="arrow_0"><img src="../media/show.gif" /></div><div style="margin-left:20px; text-align:left; font-weight:bolder; font-size:14px">SECTION ONE TITLE</div> <div class="collapsed" style="margin-left:20px; margin-right:30px; text-align:left; display:none">Section one text text text text text text text text text text text text text text text text text text text text text text </div> <div style="float:left" id="arrow_1"><img src="../media/show.gif" /></div><div style="margin-left:20px; text-align:left; font-weight:bolder; font-size:14px">SECTION TWO TITLE</div> <div class="collapsed" style="margin-left:20px; margin-right:30px; text-align:left; display:none">Section two text text text text text text text text text text text text text text text text text text text text text text </div> <div style="float:left" id="arrow_2"><img src="../media/show.gif" /></div><div style="margin-left:20px; text-align:left; font-weight:bolder; font-size:14px">SECTION THREE TITLE</div> <div class="collapsed" style="margin-left:20px; margin-right:30px; text-align:left; display:none">Section three text text text text text text text text text text text text text text text text text text text text text text </div> <div style="float:left" id="arrow_3"><img src="../media/show.gif" /></div><div style="margin-left:20px; text-align:left; font-weight:bolder; font-size:14px">SECTION FOUR TITLE</div> <div class="collapsed" style="margin-left:20px; margin-right:30px; text-align:left; display:none">Section four text text text text text text text text text text text text text text text text text text text text text text </div> upon executing the function, the result is the text for sections one and three being expanded and the arrows for one and two being changed. why? what am i doing wrong?

With the current code, no matter what cell is clicked, the alert box displays the same number, which is the last number in my array. The variable, princ, is just being overwritten rather than writing code to each the cell with the proper value. Help is appreciated. Thanks. Code: for(i=0;i<=3;i++){
document.writeln('<tr>');
document.writeln('<th>'+(periodArray[i])+'</th>');
for(j=0;j<=2;j++){

document.writeln('<td onclick="(calculateInterest(princ,1,1))">$'+principleArray[j][i]+'</td>');
}
document.writeln('</tr>');

function calculateInterest(principle,rate,period){
totalInterest = principle * rate * period;
totalLoanCost = principle + totalInterest;
alert('Total Interest: '+totalInterest+'\n'+'Total Loan Cost: '+totalLoanCost);
}
Hi Guys, I have a PHP loop region, which repeats all completed projects for each customer, then displays all jobsheets linked to those projects. I have a javascript show/hide function, which will only show the jobsheets when the project link is clicked. Without this javascript, the PHP loop works perfectly, but all the information is displayed. How can I use the show/hide function and still show all the jobsheets for completed projects? Code: function toggle2(id, link) {
var e = document.getElementById(id);
if (e.style.display == '') {
e.style.display = 'none';
link.innerHTML = '<img src="../Images/plus.gif" border="0" >';
} else {
e.style.display = '';
link.innerHTML = '<img src="../Images/minus.gif" border="0" >';
}
}
PHP Code: <table> <tr> <th>Project / Job</th> <th>Language</th> <th>Words (Net)</th> <th>Shipped</th> </tr> <?php $previousProject = ''; if ($totalRows_rsComplete_Cust > 0) { // Show if recordset not empty while ($row_rsComplete_Cust = mysql_fetch_assoc($rsComplete_Cust)) { if ($previousProject != $row_rsComplete_Cust['projid']) { // for every user, show the user name ?> <tr> <td colspan="4"><a href="#" onclick="toggle2('<?php echo $row_rsComplete_Cust['projid']; ?>', this)"><img src="../Images/plus.gif" border="0" /></a><?php echo $row_rsComplete_Cust['projid']; ?></td> </tr> <?php $previousProject = $row_rsComplete_Cust['projid']; } ?> <tr id="<?php echo $row_rsComplete_Cust['projid']; ?>" style="display:none"> <td><a href="jobsheet_details.php?id=<?php echo $row_rsComplete_Cust['jobid']; ?>&proj=<?php echo $row_rsComplete_Cust['projid']; ?>"><?php echo $row_rsComplete_Cust['jobname']; ?></a></td> <td>LANGUAGE</td> <td>WORD NET</td> <td>YES / NO</td> </tr> <?php }} // Show if recordset not empty ?> </table> Ok javascript gurus, could someone help me out with a simple script? I have an array that I want to loop through and display the values of the array on the page as it loops (so I guess there should be a slight delay before the next one appears over it). I want to loop though until a button is clicked. Help? Hi There, Below is some very basic html/javascript that asks for a user to enter a number in an input text box and then a button is pressed it writes out a line that number of times. It works, but when run in firefox the pages always seems to continue to load... that is, the cursor is continuously that when a page is loading (an arrow with a little circle) and the status bar in the bottom right hand corner seems to be always be at zero. It seems to be something in the for loop as when this is take out it works. Seems to work in IE however? Any ideas? Is this a FireFox thing or am I not terminating the loop properly? Code: <html>
<head>
<script type="text/javascript" language="javascript">
<!--
function writeloop(){
var noTimes = document.theForm.theAmount.value;
for(x=0;x<=noTimes;x++){
document.write("A line!"+"<br />");
}
}
function cleantext(){
document.theForm.theAmount.value="";
}
//-->
</script>
<title>Write Loop</title>
</head>
<body>
<form name="theForm" action="#">
<input type=button value="Press me" onclick="writeloop();" />
<br /><br />
Enter the amount of times: 
<input type=text name="theAmount" value="blah" onfocus="cleantext()"/>
</form>
</body>
Many thanks! Below is the code. My function: Code: function swap_content(id1,id2)
{
var tmp = document.getElementById(id1).name;
var theval = document.getElementsByName('primary_propertyp_id')[0].value;
document.getElementById(id1).name = document.getElementsByName('primary_propertyp_id')[0].name;
document.getElementsByName('primary_propertyp_id')[0].name = tmp;
document.getElementById(id2).id = document.getElementById('primary').id;
document.getElementById('primary').id = 'addressid_'+theval+'_div';
}
Applicable Code for primary info: Code: <div id="primary"> <label>primary to secondary:</label><input name="primary_propertyp_id" type="text" id="addressid_<? echo $row['primary_property_id']; ?>" value="<? echo $row['primary_property_id']; ?>"/> </div> Applicable Code for secondary info/link to change: Code: echo "<div id=\"addressid_" . $properties_row['id'] . "_div\">"; echo "<a href=\"#\" onclick=\"swap_content('addressid_" . $properties_row['id'] . "','addressid_" . $properties_row['id'] . "_div'); return false\">Make Primary</a>"; echo "<input id=\"addressid_" . $properties_row['id'] . "\" name=\"addressids[]\" value=\"" . $properties_row['id'] . "\" type=\"text\">"; echo "</div>"; This is running through a PHP loop so it's making multiple divs and links for the secondaries. I am wanting to be able to swap out any of them to make them 'primary'....this works for the first click, but after the first click it makes every div id and input name the same as the first that was clicked. It's also not working AT all if i click on the bottom link first, then a link above it. Top-down works, bottom-up doesn't...Please help Thanks in advance, Jeremy |
